PCM1716E/2KG4

ADCs/DACs - Special Purpose Overview

The PCM1716E/2KG4 is a stereo digital-to-analog converter featuring a 24-bit resolution and support for sampling frequencies up to 96kHz. It utilizes an enhanced multi-level delta-sigma modulator architecture with an internal 8x oversampling digital filter. The device operates on a single +5V supply and accepts standard, I2S, or left-justified audio data formats via a serial interface. Key performance metrics include a dynamic range of 106dB and a signal-to-noise ratio of 106dB at 44.1kHz. It is housed in a 28-lead SSOP package.

ADCs/DACs - Special Purpose Procurement Notes

Verify the component matches the specific ordering suffix G4, which indicates lead-free status and RoHS compliance. Confirm the package type is SSOP-28 and the operating temperature range is -25°C to +85°C. Ensure the source documentation aligns with the Burr-Brown Texas Instruments specifications for the PCM1716 series.

ADCs/DACs - Special Purpose Selection Notes

Select this component for mid-to-high grade digital audio applications requiring 24-bit resolution and 96kHz sampling rates. It supports 16-, 20-, and 24-bit input data words. The device offers flexible control modes, including software-controlled three-wire interface and hardware mode for static function selection such as de-emphasis and mute.

ADCs/DACs - Special Purpose Part Context

The PCM1716 is part of the Burr-Brown (now Texas Instruments) SoundPlus family of audio DACs. It was designed to provide high dynamic performance and reduced jitter sensitivity compared to typical one-bit delta-sigma converters. The device integrates an internal oscillator and digital filter, simplifying system design for audio playback equipment.

ADCs/DACs - Special Purpose Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing system clock requirements (256fs, 384fs, 512fs, or 768fs) and pin configurations if considering alternative devices.

ADCs/DACs - Special Purpose FAQ

What are the selectable digital filter roll-off characteristics?

The PCM1716 offers two selectable digital filter roll-off performances: sharp roll-off and slow roll-off, allowing customization based on specific application requirements.

How is the zero detect mute function controlled?

The zero detect mute function can be enabled or disabled via the IZD bit in Register 3. When enabled, if input data is continuously zero for 65,536 BCK cycles, the output is forced to bipolar zero.

What is the maximum analog output voltage range?

The analog output full-scale voltage is 0.62 times VCC (peak-to-peak), with a center voltage of 0.5 VCC when operating on a single +5V supply.
